Artemis II Core Stage Integration – Complete!

Teams with NASA’s Exploration Ground Systems and primary contractor Amentum integrate the SLS (Space Launch System) Moon rocket with the solid rocket boosters onto mobile launcher 1 inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center on Sunday, March 23, 2025. Artemis II is the first crewed test flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.

A New Proof Smooths Out the Math of Melting

Imagine an ice cube floating in a glass of water. Eventually, it will melt down to a tiny frozen speck before disappearing. As it shrinks, its surface gets smoother, and any irregularities or sharp edges gradually vanish. Mathematicians want to understand this process in greater detail, to be able to say exactly how the surface of the ice — or, say, the shape of a gradually eroding sandcastle… Source

AI is great at predicting text. How well can it guide robots?

It seems like artificial intelligence is everywhere in our virtual lives. It’s in our search results and our phones. But what happens when AI moves out of the chat and into the real world? NPR science editor and correspondent Geoff Brumfiel took a trip to the Intelligence through Robotic Interaction at Scale Lab at Stanford University to see how scientists are using AI to power robots and the large hurdles that exist for them to perform even simple tasks.
